Abstract: Helium in metals is investigated for different reasons: most interesting for the materials technology is the so-called "helium embrittlement". This is the effect of the sometimes dramatically reduced ductility and lifetime of structural materials in advanced fission reactors induced by helium. Similar effects are expected or respectively feared in future fusion reactors or large (high flux) particle accelarators (e.g. spallation neutron sources). On the other hand the system helium-metal has also gained interest in basic physical science because of special properties (e.g. ist practically unsoluable in metals). This work reviews the present knowledge of the physical properties of the helium precipitates (so-called helium bubbles) in metals as weil as the effects of them on the mechanical properties of structural metals and alloys. It should be emphasized that this work more describes the present understanding of the underlying mechanisms of the observed effects than completely lists all the work done in the field.
